The public advantage should be the single object of the king and his counsellors, or should at least be preferred to every private interest. It is impossible to estimate the good which a prince and his ministers may do if they religiously follow this principle, or to estimate the disasters which must fall upon the state whose public interests are ruled by private considerations. True philosophy, the Christian law, and the art of statesmanship, unite to teach this truth. The prosperity which Spain has enjoyed for several centuries has been due to no other cause than that her council has consistently preferred the interests of the state to all others, and most of the calamities which have visited France have been due to the preference of private advantage. It is easy for princes to consent to the general regulations of their state, because in making them they have only reason and justice before their eyes, and men willingly embrace reason and justice when there are no obstacles to turn them from the right path. But when occasions arise for putting these regulations into practice, we do not find that princes always show the same firmness, for then the interests of factions and of minorities are pressed upon them; pity, sympathy, favour, and importunities solicit them and oppose their just designs; and they have not always strength enough to conquer themselves and to despise these partial considerations, which ought to have no weight at all in the affairs of the commonwealth. It is on these occasions that they must gather up all their strength against their weakness, and remember that God has placed them there to safeguard the public interest. _The Power of Kingship_ Power is one of the most necessary conditions of the greatness of kings and of the happiness of their government, and those who have to do with the conduct of a state should omit nothing which may enhance the authority of their master and the respect in which he is held by all the world. As goodness is the object of love, power is the cause of fear; and fear, founded in esteem and reverence, makes dutiful conduct the interest of every subject, and warns all foreigners not to offend a prince who can harm them if he will. I have said that the power of which I speak must be founded on esteem, and I will add that if it be otherwise founded it is dangerous in the extreme. Princes are never in a more perilous position than when they are the objects of hatred or aversion rather than of a reasonable fear.
